Q: Why do I receive the message: Error: Unable to check out a
license when I attempt to load Altera’s original equipment manufacturer
(OEM) version of the ModelSim software?
A: This error occurs if you have not completed the license install portion of
the ModelSim software installation process. This error applies only to the
ModelSim-Altera software for versions prior to 5.5e.
Reinstall the ModelSim OEM software if the path to your ModelSim OEM
license is not correctly specified. Follow the steps in “ModelSim-Altera
Edition Software on a PC for Versions Prior to 5.5e” on page 83.
Additionally, ensure that your floating license and the mgcld license
daemon are valid and compatible with the required ModelSim-Altera mgcld
daemon. Refer to “Unable to Check Out License” on page 83 for more
information.
